The researchers found that a unique protocol of treatments with high-pressure oxygen in a pressure chamber can reverse two major processes associated with aging and its illnesses: the shortening of telomeres (protective regions located at both ends of every chromosome) and the accumulation of old...
Triplet–triplet annihilation (TTA) upconversion (TTA-UC) is an important means to implement anti-stokes wavelength conversion using low incoherent light irradiance (<100 mW/cm2)1,2,3. This photochemical process typically involves a pair of sensitizer/annihilator molecules, in which annihilator mol...
